[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [PATCH v9 0/7] Introduce generic headers
Some headers are common between several architectures, so the current patch series provide them. Another one reason to have them as generic is a simplification of adding support necessary to make a complete Xen build as it was/is being done in the patch series [1] and [2]. Also, instead of providing generic/stub headers, it was used "#ifdef CONFIG_* #include <asm/*.h> #endif" instead of providing empty headers. This patch series is a pre-requisite for "Enable build of full Xen for RISC-V" [3]. [1] https://lore.kernel.org/xen-devel/cover.1694543103.git.sanastasio@xxxxxxxxxxxxxxxxxxxxx/ [2] https://lore.kernel.org/xen-devel/cover.1692181079.git.oleksii.kurochko@xxxxxxxxx/ [3] https://lore.kernel.org/xen-devel/cover.1700761381.git.oleksii.kurochko@xxxxxxxxx/ --- Changes in V9: - Drop the patch "[PATCH v8 1/7] automation: ensure values in EXTRA_FIXED_RANDCONFIG are separated by new line" as better solution was suggested. - introduce new follow-up patch for "xen/asm-generic: introduce generic device.h" ( it can be merged with patches 4,5 of this patch series ). - All other changes please find in revision log to a patch. --- Changes in V8: - Add Acked-by Acked-by: Tamas K Lengyel <tamas@xxxxxxxxxxxxx> for patches: [PATCH v7 4/7] xen/asm-generic: ifdef inclusion of <asm/mem_access.h> [PATCH v7 3/7] xen/asm-generic: introduce stub header monitor.h - Update the commit messages for patches: [PATCH v7 5/7] xen/asm-generic: introduce generic device.h [PATCH v7 6/7] xen/arm: switch Arm to use asm-generic/device.h - Drop #ifdef HAS_PCI in asm-generic/device.h to be consistent with other pci-related things in the header. - Code styles fixes. --- Changes in V7: - The following patches were dropped because of rebasing as they were merged to staging: - [PATCH v6 3/9] xen/asm-generic: introduce generic div64.h header - [PATCH v6 6/9] xen/asm-generic: introduce stub header softirq.h - [PATCH v6 7/9] xen: ifdef inclusion of <asm/grant_table.h> in <xen/grant_table.h> - [PATCH v6 8/9] xen/asm-generic: ifdef inclusion of <asm/mem_access.h> - [PATCH v6 5/9] xen/asm-generic: introduce stub header numa.h was dropped becaus of the patch: "[PATCH v2] NUMA: no need for asm/numa.h when !NUMA" - Drop definition of arch_monitor_domctl_event for PPC. - define arch_monitor_domctl_event in asm-generic/monitor.h. - Add "define HAS_ARCH_MONITOR_DOMCTL_EVENT" in arm/.../monitor.h as it has arch specific implementation. - keeping DEVICE_PCI_HOSTBRIDGE available for every build based on the reply: https://lore.kernel.org/xen-devel/926a5c12-7f02-42ec-92a8-1c82d060c710@xxxxxxx/ - add comment above enum device_type.h with explanation about DEV_TYPE_MAX. - drop #ifdef HAS_PCI around "(device_get_class(dev) == DEVICE_PCI_HOSTBRIDGE))" in ARM code. - separate patch "[PATCH v6 9/9] xen/asm-generic: introduce generic device.h" into 3 patches. --- Changes in V6: - Fix the build script to work properly with EXTRA_FIXED_RANDCONFIG. - Introduce separate randconfig yaml with fixed configs for RISC-V. - Disable CONFIG_GRANT_TABLE and CONFIG_MEM_ACCESS for PPC and RISC-V. - Remove change in Kconfig/common for CONFIG_GRANT_TABLE and CONFIG_MEM_ACCESS. - Rebase on top of the latest staging. --- Changes in V5: - Update the patch series message as patch related to delay.h was merged. - Rebase on top of staging because half of the patches of the patch series were merged to staging branch. - Add A-by for some of the patches. - Add "depends on X86 || Arm" for CONFIG_GRANT_TABLE and CONFIG_MEM_ACCESS to be sure it won't be turned on by randconfig in CI. - Partly switch Arm and PPC to asm-generic/monitor.h. - Some other minor changes --- Changes in V4: - Update the cover letter message - Add Reviewed-by/Acked-by for patches: [PATCH v3 01/14] xen/asm-generic: introduce stub header paging.h [PATCH v3 03/14] xen/asm-generic: introduce generic hypercall.h [PATCH v3 04/14] xen/asm-generic: introduce generic header iocap.h [PATCH v3 05/14] xen/asm-generic: introduce stub header <asm/random.h> [PATCH v3 06/14] xen/asm-generic: introduce generic header percpu.h [PATCH v3 07/14] xen/asm-generic: introduce generalized hardirq.h [PATCH v3 08/14] xen/asm-generic: introduce generic div64.h header [PATCH v3 09/14] xen/asm-generic: introduce generic header altp2m.h [PATCH v3 10/14] xen/asm-generic: introduce stub header monitor.h [PATCH v3 11/14] xen/asm-generic: introduce stub header numa.h [PATCH v3 12/14] xen/asm-generic: introduce stub header softirq.h - Fix some code style and minor issues. - Use asm-generic version of device.h for Arm and PPC. --- Changes in V3: - Update the commit message of the cover letter. - Drop the following patch as it can be arch-specific enough: * [PATCH v2 09/15] xen/asm-generic: introduce generic header smp.h - Drop correspondent arch specific headers and use asm-generic version of a header. - Back to the patch series patches: * xen: ifdef inclusion of <asm/grant_table.h> in <xen/grant_table.h> * xen/asm-generic: ifdef inclusion of <asm/mem_access.h> --- Changes in V2: - Update the commit message of the cover letter. - Drop the following patches because they are arch-specific or was sent as a separate patch: - xen/asm-generic: introduce stub header event.h - xen/asm-generic: introduce stub header spinlock.h - [PATCH v1 03/29] xen/asm-generic: introduce stub header cpufeature.h - [PATCH v1 07/29] xen/asm-generic: introduce stub header guest_atomics.h - [PATCH v1 10/29] xen/asm-generic: introduce stub header iommu.h - [PATCH v1 12/29] xen/asm-generic: introduce stub header pci.h because separate patch was sent [5] - [PATCH v1 14/29] xen/asm-generic: introduce stub header setup.h - [PATCH v1 15/29] xen/asm-generic: introduce stub header xenoprof.h because of [3]. -

[PATCH v1 24/29] xen/asm-generic: introduce stub header guest_access.h - [PATCH v1 25/29] xen/asm-generic: introduce stub header irq.h ( probably not so generic as I expected, I'll back to it if it will be necessary in the future ) - [PATCH v1 28/29] xen/asm-generic: introduce stub header p2m.h ( probably not so generic as I expected, I'll back to it if it will be necessary in the future ) - For the rest of the patches please look at changes for each patch separately. --- Oleksii Kurochko (7): automation: introduce fixed randconfig for RISC-V xen/asm-generic: introduce stub header monitor.h xen/asm-generic: ifdef inclusion of <asm/mem_access.h> xen/asm-generic: introduce generic device.h xen/arm: switch Arm to use asm-generic/device.h xen/ppc: switch PPC to use asm-generic/device.h xen/asm-generic: fold struct devarch into struct dev automation/gitlab-ci/build.yaml | 14 ++- xen/arch/arm/device.c | 5 + xen/arch/arm/domain_build.c | 2 +- xen/arch/arm/gic-v2.c | 4 +- xen/arch/arm/gic-v3.c | 6 +- xen/arch/arm/gic.c | 4 +- xen/arch/arm/include/asm/Makefile | 1 + xen/arch/arm/include/asm/monitor.h | 25 +--- xen/arch/arm/p2m.c | 1 + xen/arch/arm/traps.c | 1 + xen/arch/arm/xen.lds.S | 2 + xen/arch/ppc/configs/ppc64_defconfig | 1 + xen/arch/ppc/include/asm/Makefile | 1 + xen/arch/ppc/include/asm/device.h | 53 -------- xen/arch/ppc/include/asm/mem_access.h | 5 -
